Did Khloe Kardashian achieve her killer new body through lipo?

Khloe Kardashian has never looked better, and now someone's claiming she didn't achieve her fab new figure on her own.

Radar Online is reporting that Khloe went under the knife to slim down and tone up.

"Khloe got serious lipo done on her waistline, tummy and legs over three months ago," a source told the website.

Whether or not she took that particular plunge, who could blame her for considering it? Though we've always loved Khloe's fuller figure, it can't be easy being constantly compared to her thinner sisters.

"She's tired of looking enormous next to her younger sisters and is happy to step aside and let Kim take the family butt crown," the insider adds. "She looks great and is finally feeling very positive about her body image."

It shows. Khloe, 30, was the picture of confidence in a sheer body-hugging black dress during a recent dance sesh in Las Vegas.

But why mess with near-perfection? Khloe moves like the ones in the video below just wouldn't be the same.
